Gather by ChunkId

Required Methods§

Source

unsafe fn take_chunked_unchecked<const B: u64>( &self, by: &[ChunkId<B>], sorted: IsSorted, avoid_sharing: bool, ) -> Self

Gathers elements from a ChunkedArray, specifying for each element a chunk index and index within that chunk through ChunkId. If avoid_sharing is true the returned data should not share references with the original array (like shared buffers in views).

§Safety

This function doesn’t do any bound checks.

§Safety

This function doesn’t do any bound checks.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
